Corsair RMx Series Fully Modular 850W Power Supply Review

Introduction and Features

Introduction

Corsair has just expanded their RM Series of PC power supplies to include a third line, the RMx Series, in addition to the original RM and RMi Series. The new RMx power supplies will be available in 550W, 650W, 750W, 850W and 1000W models and are designed by Corsair and built by Channel Well Technologies (CWT). We will be taking a detailed look at the new RM850x 850W PSU in this review.

The RMx Series power supplies are equipped with fully modular cables and optimized for very quiet operation and high efficiency. RMx Series power supplies incorporate Zero RPM Fan Mode, which means the fan does not spin until the power supply is under a moderate to heavy load. The cooling fan is designed to deliver low noise and high static pressure. All of the RMx power supplies are 80 Plus Gold certified for high efficiency.

The Corsair RMx Series is built with high-quality components, including all Japanese made electrolytic capacitors, and Corsair guarantees these PSUs to deliver clean, stable, continuous power, even at ambient temperatures up to 50°C.

Establishing an accurate load is critical to testing and evaluating a PC power supply. PCPerspective’s power supply test bench can place a precise DC load on the PSU under test. Each power supply is tested under controlled, real-world conditions up to its maximum rated load (at 40ºC), using both 115 VAC and 240 VAC line voltage. Our current suite of tests includes:

Nice review. I was planning on using this PSU in my next build. Going for a black and white theme to it, and this is one of the few PSUs that matches those colors. The detailed pics of the cables was nice also.
